我国东部主要类型金矿床的找矿标志

THE INDICATORS OF MAJOR TYPES GOLD DEPOSITS IN THE EASTERN CHINA

中国东部地区不同类型的金矿床中大多可见到Ａｕ、Ａｇ、Ｃｕ、Ｐｂ、Ｚｎ、Ａｓ、Ｈｇ及Ｍｏ等元素的异常，除Ｍｏ外，其它元素的异常与Ａｕ元素的异常为正相关。各类型矿床的异常元素组合、矿物组合及黄铁矿中微量元素的含量、氧硫同位素变化等均有一定的差异。成矿环境总的来说是富硅或富钙、贫氧的碱性环境。

It could be seen that the anomalies of elements Au,Ag,Cu,Pb,Zn,As,Hg, Mo in various gold deposits in the eastern China. They have positive correlations with Au except Mo. There exist some defference on the association of anomalous elements and minerals, the content of trace elements in pytite, the variance of sulfur's and oxygen's isotopes etc. in different types deposits. Overall, their metallogenetic environments mainly are alkalic environments of rich silicon or calcium and poor oxygen.
